Frequently Asked Questions

Can "w" and "was" be used interchangeably?
No - they are not even the same part of speech. "w" is a character and "was" a verb, so a sentence built for one is usually ungrammatical with the other.
Which is more common, "w" or "was"?
"was" is the more common of the two: it sits at frequency rank #16 in our English list, against #628 for "w". That is a wide gap, so in ordinary text the rarer spelling is the one worth double-checking.
